smart. 146.329. on model.)

To all whmn it may concern:

Be it known that we, OLE CHRISTIAN Mon- SEN, a subject of the King ofSweden and N01- way, residing at Providence, and EMANUEL ERIOKSEN, acitizen of the United States, residing at Oranston, in the county ofProvidence, in the State of Rhode Island, have invented certain new andusefulImprevements in Dust-Proof Drawers, of which the following is aspecification, reference being had therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is an isometric view ofourinvention as seen when the drawersare closed- Fig. 2 is a view of the same as seen in vertical section online 00 a: of Fig. 1 with the up-' per drawer partially out and thelower drawer entirely out. Fig. 3 is a view of the same as seen invertical section on line w a: of Fig. 1 with the upper drawer nearlyclosed and the lower drawer entirely closed. Fig. 4 is aview of saidinvention as seen in vertical section on liney y of Fig. 1.

Ourinvention relates to dust-proof drawers, and it consists of the novelconstruction and combination of the several parts as hereinafterparticularly described, and specifically set forth in the claims.

In the drawings is shown in. Fig. l a chiffonnier or case of drawers,consisting of the drawers A B and a frame, comprising the posts 0 O C O,the cross-pieces or rails D D D', the partition or dividing-strip E, thefront top rail F, the bottom rail G, and four side strips H I J K oneach side. The drawer A is supported and slidable on the ledges orflanges a of the side strips I, and the drawer B is supported andslidable on the ledges or flanges b of the side strips K.

The side strips H H have transverse vertical slots 0 0 about midwaytheir length, whose bottoms may be concave, as shown, or square, ifpreferred. In like manner the side strips J J have transverse verticalslots at d.

The drawer-covers are shown at L and M. They are rectangular in shapeand of a size to cover the top of the drawer and to project over the twosides and the back end thereof, but not to project over or cover thefront end of the drawer. Each drawer-cover has a downwardlyextendingflange e, which is adapted to shut down over the sides and back end ofthe drawer on the outside thereof, as

seen in Figs. 3 and t. Two pins N project at right angles from the sidesof the drawercover L and extend through the slots 0 c of the side stripsH H, as shown, and two pins 0 project at right angles from the sides ofthe drawer-cover M and extend through the slots 61 d in like manner.

As seen in Fig. 2, the front end of each drawer-cover has no flange. Thefront end of the drawer-cover L is beneath the lower edge of the uppercross-piece D, and the front end of the drawer-cover M is beneath theforward portion of the flanges a of the side strips I.

Itis preferable that the pinsN and 0 should be inserted in the sides ofthe drawer-covers L and M alitt'le nearer to the front than to the backof said covers, respectively.

When the drawer is pushed in, which is its normalposition, as is shownby the drawer B in Fig. 3, the drawer-cover entirely closes the top ofthe drawer and the flanges e of said cover'shut down over the two sidesand the back end of the drawer, and thus effectually keep out the dust,as also insects and vermin. When the drawer is pulled out, as isillustrated by the drawer A in Fig. 3, as long as the back end of thedrawer is in a position to the rear of the pins N the drawer-cover L ishorizontal and rests upon and is supported by the upper edges of thesides and of the back end of the drawer; but as soon as the back end ofthe drawer A comes to a position forward of the pins N, as illustratedin Fig. 2, the rear portion of the drawer-cover L being heavier than thefront portion and being ICO Fig. 2.

Fig. 2) the pins N O are at the bottoms of the slots 0 d.

In closing the drawer when it is in the position occupied by the drawerAin Fig. 2'and moving inwardly, as indicated by the arrow, the back endof the drawer first slides between the forward ends of the flanges e ofthe drawer-cover as there seen, butdoes not at once come into contactwith the under surface of the drawer-cover; but as the back end of thedrawer approaches nearer to the pins on which the drawer-coveris hung,as said drawer-cover is then in the angular position shown in Fig. 2,the continued inward movement of the drawer raises the drawercoverbodily as soon as the back end of the drawer comes in contact withthelower surface of the drawer-cover. The drawer-cover L then assumesthe horizontal position, (shown in Fig. 3,) the pins N thereof risingsomewhat in the slots 0 c of the side strips H H, as seen in saidfigure. The side flanges e shut down over the sides of the drawer. Whenthe drawer has been pushed in to its full extent, the upper portion ofthe back end of the drawer is in abutment with the inner surface of therear flange e of the drawer-cover, as is shown in the lower half of Fig.3.

Itis obvious that the pins or pivots on which the drawer-cover turns maybe placed at any position intermediate of its ends, though we preferthat they be so located that the rear portion of the drawer-cover willautomatically assume by gravity the position illustrated in Suchmovement may, however, be facilitated or wholly produced by weightingthe rear end of the drawer-cover.

The side pieces H and J serve to maintain the tilting covers L M in atrue vertical plane of movement and to prevent them from lateralmovement 01' shifting.

Suitable stop blocks or any other wellknown means are used to limit theinward movement of the drawers.

The drawers and covers may be made of Wood, metal, or any suitablematerial. By

being made single or in pairs this device is practically a unit and maybe combined in series to any desired height or length, as in fitting upstores for the keeping of merchandise and wares free from dust, insects,or vermin. Thus the cost of fixtures and furniture of stores andWarerooms may be greatly reduced.

We claim as a novel and useful invention and desire to secure by LettersPatent 1. The combination of a drawer, a frame in which said drawer isslidably mounted, and a drawer-cover adapted to cover the top of thedrawer and mounted on pivots' at its opposite sides near the centerthereof in said frame and arranged so as to have a vertical oscillationon said pivots as the drawer slides in and out, substantially asdescribed.

2. The combination of a drawer, a frame wherein said drawer is slidablymounted, a vertically-tilting drawer-cover mounted on its opposite sidesin a line forward of the central transverse line thereof upon pivotsextending into said frame, and a stop to limit the extent of the tiltingmovement of said drawercover, all arranged substantially as shown andfor the purpose specified.

3. The combination of a drawer, a frame wherein said drawer is slidablymounted and comprising two side parallel pieces each of which has avertical transverse slot at or near the center thereof, averticallyoscillating drawer cover mounted between said side piecesabove the drawer and provided with pivots which extend loosely in saidslots, respectively, and astop tolimit the oscillation'of thedrawer-cover, substantially as described.

4. The combination of a drawer, a frame wherein said-drawer is slidablymounted, and a vertically-oscillating drawer-cover mounted at or nearits center on pivots in said frame transversely thereof and provided onits sides and rear edge with a flange capable of shutting down over theupper edges of said drawers,snbstantiallyas shown anddescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
